Stack color-coded base-ten blocks into ones, tens and hundreds silos to forge target numbers. Build numbers, read the silos, and regroup ten of one place into one of the next.
Children stack color-coded blocks into ones, tens, and hundreds columns until the total matches a target, then also read a filled silo to name the number it represents. The core skills are place value in base ten and regrouping — recognising that ten ones become one ten, and ten tens become one hundred. A strong match for Grades 2–4, or any child building number sense before multi-digit addition.
A free, no-signup, no-ads math game for Grades 2–4 — practising place-value, base-ten, regrouping. Play in your browser on the KidsDoMath games hub or explore more Arithmetic games.
